摘要： PROBLEM TO BE SOLVED: To provide a fuel injection valve capable of injecting fuel in optimal fuel injection ratios in various engine operation areas.
SOLUTION: This fuel injection valve has a first nozzle port group 14, a second nozzle port group 15, a control room 20, a first needle valve 12 and a second needle valve 13. The first needle valve 12 opens and closes a nozzle port of the first nozzle port group, and the second needle valve opens and closes a nozzle port of the second nozzle port group, and a lift of the first needle valve and the second needle valve is controlled by pressure of fuel in the control room. An inflow-outflow flow rate changing means 30 is also provided for changing a fuel flow rate flowing in the control room or a fuel flow rate flowing out of the control room when lifting the needle valve. Change control of the fuel flow rate by the inflow-outflow flow rate changing means is performed based on common rail pressure of a fuel supply source.
